the cap's interior, an especially well made piece, far superior to the later variety one sees more frequently (which is not very....) Its owner was commissioned in the Sta. 32 (Heidelberg) in early 1935, which also sort of corresponds to when the cap was likely made. The longer one is around this stuff, one finds a lot of it vacuumed out of what was the US zone of occupation, that is such places as Heidelberg and Munich...
"Stirndrueckfrei durch Gummipolster" = free of pressure on forehead via rubber pad
--but it sounds better in German.
There is another cap of this type in Texas which came with a black Stammabteilung uniform. It has an RFSS tag, which this one does not.
I believe this sort of cap was an early variety of RZM'd cap, i.e. from the 2d half of 1934 or so.
See excerpt from SS price list of 1934. The cap in question is item # 714, I think...
happy collecting, FB
the black uniform of the Stammabteilung in question....the cap is another example, in fact, it is in the Shea and Beaver book itself....somehow.
